` Specification of Letters Patent.

Application filed February 6, 1913.' Serial N o. 746,581.

To all whom t may concern Be itknown that I, EnwARD MORRIS NORTON, a citizen of theUnited States, residing in the borough of Manhattan, 1n thecity, county, and State of New York, have invented certain nev.7 and useful Im` provements in Vaporizer Attachments, of

which the following is a full, clear, and

exact description, reference being had to the accompanying drawings, forming a partof this specification.

This invention relates to improvements 1n the construction of vaporizers, such as used in connection with certain types of internal combustion engines, and its prlmary object is to provide a simple and eilicient device whereby the formation of so-ot.and carbon.

deposits.. in the vaporizing chamber will be prevented.

`A further object of this invention 1s to provide a vaporizer cleaning de vlce of a simple and novel construction Whlch can be readily attached to the vaporizer ofan engine without necessitating any change In the construction of the same.

With these and other objects in View. as will more fully "appear as the descrlption proceeds, this invention conslsts of certain improved constructions and arrangements of partsv as will`be-hereinafter descrlbed and claimed' in the appended claims. v

Internal combustion engines and particularlythose types of oil engines providedwith a 'vaporizer in which a charge o f oilis injected and vapo-rized ,previous to its admission to the cylinder, are generally. not entirely freefrom inconyeniences, especlally in regard to imperfect combustion and -co-nsequent formation *of injurlous deposltsfo-n the inside surface ofthe vaporizer, requir'm the same to be cleaned at the end ofeac day of service, Such imperfections are 'also' yto be found in those englnes where the mixis placed in fro-nt connection. Vaporizing is'conducted in the interior of a combustion chamber, which is l so .arranged that the heat ofthe ex losion maintains it' at a temperature consi erably high to enable the oil to be vaporized by mere injection upon. the hot surface. On the p suction stroke of the piston, air is taken into the cylinder through the air inlet valve without passlng through the vaporizer chamber.

` In the meantime the oil which is thrown into the vaporlzer j is 'vaporizing and diffusing" itself through the vaporizer chamber mixin with the hot products-of combustion left by the preceding explosion..l During this Stroke therefore, the air enters through the cylin; der and the vapor formed from the oil is almost entirely confined to the combustion chamber. On the return stroke of the piston airv is forced through the bottle neck connection-into the combustion chamber and is there mixed with the it. As the compression morel air is forced into the vaporizer or combustion chamber, and just as compression is completed the mixture attains proper explosive pro ortions. The surface ofthe chamber is su cientl hot to cause explosion, under the pressure o which the piston moves in its working stroke.

is usually necessary to Vapor contained in clean the vaporizer 'chamber of these engines at theend of each 'working day', soot or other unburned particles of combuson account of the deposit of tionV within the same. This is possibly formed in the period of relative rest of the 4products-of combustion contained within the v aporizerv chamber at the end of the working stroke of the piston and during the exand therefore I have devised.

haust stroke; means whereby such burned particles are continually removed as they are formed, in-

cidentally sald means being at the-same time .helpful 'toward forming an explosive mix-v ture which explodes more readily and which is more active in itseffects.

proceeds more and .As stated before, it;

tates a .special construction of the cylinder f connects therewith by means of a bottle-neck 65 The annexed drawings are intended to illustrate one of the ways' of putting my invention into practice, and in the same Figure 1 is ai detail view Ain elevationy artly sectioned showing the vaporizer cham er of a Hornsby-Ackroyd engine with my device attached, and Fig. 2' is a rear elevation de! -tail view in an enlarged scale, showing the' preferred way of holding the cock controllino` the iow of'water through my device, at different graduations of opening.

Referring to said drawings, 10 is the vaporizer chamber communicating with the inside of thecylinder 11, by means of a bottleneck connection 12; said vaporizer chamber `is'provided-with water jacket 13, 14 representing the inlet to said water jacket. 'The vaporizer chamber is fitted with a cap 1,5,

` box 17 to the vaporizer chamber'. Said box is provided with a suction pipe 18, having a flaring portion 19, which comes quite close to the surface of the vaporizer cap; said suction pipe is preferably pivotally mounted on the top of said box 17, as shown in 20,

the object of this being the possibility of removing the same from its normal position close to the vaporizer cap when it isnecessary to start the engine and therefore to heat said cap from the outside. Pipe 16 is provided with a stop-cock 21, and between said pipe 16 and the inside of box 17 is also provided a check `valve 22, openin toward the vaporizer chamber. It is obvious that when stop cock 21 is open, the suction exerted by the piston during its suction stroke will cause an inflow of air between flaring portion 19, andthe surface of vaporizer cap 15, through suction pipe 18, box `17 and pipe 16, to the inside o the vaporizer chamber; and moreover, said air being forced to pass close to the surface of vapo-rizer cap 15, A,which is incandescent, will be heated'.I IDuring the exhaust andthe compression strokes of the piston, check valve 22 will remain closed and therefore no gases or` products of combustion will come .but of the va ori'zer chamber. To further increase the e ciency of my device, I provide means whereby said heated air takes up steam or moisture during its course, conveying the same to the vaporizer chamber; and to this end I providea pipe 23 with a tank or receptacle 24; said connection can be opened or closed by means of a stop cock 25. Said tank or receptacle 24 is provided with' filtering means vfor the water coming from the water jacket, these consisting for instance, of partitions of fine wire gauze 26, inserted between the lower and the upper part of said tank or receptacle; these will prevent the entrance of slight particles, which may be contained in the water, to box 17 and from there to the insideV of the vaporizer chamber. At the upper part of said tank or receptacle, I providea faucet 27 leading to a funnel like portion 28, provided on the top -of box 17 the flow of water from said faucet can be controlled by a cock 29, which can be secured at different 'degrees of opening; this can be effected in any desired manner, a simple way being that illust-rated in Fig. 2, from which it is seen that the elongated handle 30 of said cock can be retained by its own elasticity in one of the indentations .provided in a rack 3l.

` 32 designates a partitionbetween the upper and lower portion of box 17, said partition consisting preferably of fine metallic w1re gauze.

The iiow of water Nthrough faucet 27 is due to gravity, 'the difference in level between the upper part of the water jacket j and said faucet being quite sufficient for this purpose. Said water gradually falls on wire gauze 32, which is heated by the hot air coming from suction pipe 18, and spreading on the surface of said wire gauze, is taken up by said hot air partly in the form of moisture, the mist thus formed reaching the vaporizer chamber in the best condition for removing the deposits on the surface thereof I have found this device to be extremely efficient, so much so that the cleanin of the vaporizer at the end of each wor ting day is no longer needed, it being sutlicient to clean theA same once every two or three months. y

It is obvious that in orderto carry my invention into practice, it is not necessary'to closely follow the details of the structurel illustrated and described. The same are susceptble of being modiie'd to a considerable extent, without any radical departure being made from the fundamental idea of` my invention; therefore I reserve myself the right of bringing to my invention all those changes and modifications which may be deemed useful or necessar to jcomply with the requirements of dfi erent cases, and

which may enter. fairly into the scope of the appended claims.
